It is still present in <br />the reclamation environment, but not as abundant as in the natural vegetation. Where it <br />does occur it seems to have expanded a bit. <br />Individual Reclamation Areas: This is a new section added this year. It <br />describes the bond release status of the five revegetation areas that have been done <br />since 2007 which utilized the new seed mixture in the amended plan. <br />In general, these five areas have shown similar patterns of development with <br />variations occurring along a moisture gradient and a secondary variability related to <br />soil nutrition. On the whole, all five areas have exhibited a strong trend toward <br />developing a vegetation that is similar to the natural undisturbed vegetation. This is <br />quite different from older revegetation areas where the planted species were not <br />representative of the natural vegetation. In those locations, convergence with the <br />natural vegetation only occurred after severe drought killed off the introduced species <br />and invasion from adjacent natural vegetation gained the upper hand in the <br />development. In some areas of the older revegetation that shift has been hindered by a <br />Status report for 2009 due July 15, 2010 Page 8 of 13 <br />
